Show affiliationsIsomeric states in 254No were investigated using a calorimetric method. Two different isomers were found with half-lives of T1/2=266±2 ms and T1/2=184±3 μs, respectively. The dominant decay path of the 184 μs isomer proceeds via states feeding the longer-lived 266 ms isomer. The 266 ms isomer in turn decays via a two-quasi-particle K=3 band to the ground-state band. The full decay path was observed with the GREAT spectrometer located at the focal plane of the gas-filled separator RITU at the Accelerator Laboratory in Jyväskylä. This work sheds light on the two-quasi-particle structure in this transfermium nucleus.
